Hi, I noticed recently many recovery threads taking hours to run and the size of the data is quite small to cause this (MBs) what could be causing this ? I also see huge skew gap of shard allocation across my cluster. It's currently in **green** status though. `GET _cat/recovery?v` ![image](https://us1.discourse-cdn.com/elastic/original/3X/e/d/ed3e1d99df4596fa0cb783af92bebda8cda803aa.png) ---

Hi @viniciof Which version are you using? Did you change any recovery settings? ---
